Chromium carbide is useful in the surface treatment of metal components. Chromium carbide is used to coat the surface of another metal in a technique known as thermal spraying. Cr 3 C 2 powder is mixed with solid nickel-chromium. This mixture is then heated to very high temperatures and sprayed onto the object being coated where it forms a ...
Coating mechanical parts can help with problems of corrosion, adhering, high-temperature and mechanical wear thus reducing unplanned repairs and loss of production. The features of PCC coatings are: obtaining protective layers with high adhesion strength on parts and products made of various engineering materials including metal and non-metal ...
In chemistry, a carbide usually describes a compound composed of carbon and a metal. In metallurgy , carbiding or carburizing is the process for producing carbide coatings on a metal piece. [ 1 ]
The resulting coating has low porosity and high bond strength. [1] HVOF coatings may be as thick as 12 mm (1/2"). It is typically used to deposit wear and corrosion resistant coatings on materials, such as ceramic and metallic layers. Common powders include WC-Co, chromium carbide, MCrAlY, and alumina.
The high hardness and corrosion resistance of unalloyed chromium makes it a reliable metal for surface coating; it is still the most popular metal for sheet coating, with its above-average durability, compared to other coating metals. [75] A layer of chromium is deposited on pretreated metallic surfaces by electroplating techniques. There are ...

Detonation spray coatings are applied using a detonation gun (D-gun) which is composed of a long-water-cooled metal barrel containing inlet valves for introducing gases and powders into the chamber. [4]
[1] [2] In addition to the multicolored coatings mentioned, he has also been able to obtain monochrome coatings, and he called that technique metallocromia. Electrochemical coloring of metals based processes are black, green and blue nickel plating, black chromium plating, black rhodium plating and black ruthenium plating.
